Description

TECHNICAL FIELD

[0001] The invention relates to a method for making an emergency call in a vehicle according to the preamble of claim 1. BACKGROUND

[0002] Making an emergency call is an important component of the rescue chain. Here, the so-called 5 W principle is as follows:

[0003] - Where does the incident take place?

[0004] - Who is calling?

[0005] - What happened?

[0006] - How many people are affected?

[0007] - Wait for a callback!

[0008] But it is often difficult for the affected person to comply with the above-mentioned principles. In particular, the caller often has difficulty locating the accident site or the emergency site. In addition, there is often a lack of an accurate description of the emergency event.

[0009] It is also known that a smartphone can be located when an emergency call is triggered. In addition, an emergency call application for people with speech and hearing impairments is also known.

[0010] US 2020 / 0029194 A1 describes a headlamp assembly for use in a vehicle and for reporting an emergency condition to a dispatcher, wherein the headlamp assembly comprises a housing forming a cavity, a processor mounted in the cavity, a wireless transceiver carried by the housing and connected to the processor, at least one first sensing device for detecting at least one first condition during operation of the vehicle, wherein the first sensing device is in communication with the processor, wherein the processor is programmed to receive data from the at least one first sensing device, analyze the received data to assess the likelihood of an emergency condition existing, and automatically initiate a wireless emergency condition reporting communication with an emergency dispatch center when the likelihood of an emergency condition is determined to be greater than a first threshold. SUMMARY

[0011] It is the task of the invention to propose a new method for making an emergency call in a vehicle.

[0012] According to the invention, the task is solved by a method for making an emergency call in a vehicle having the features of claim 1.

[0013] - A method for making an emergency call in a vehicle is proposed, wherein when an emergency call number is dialed via a mobile terminal device, an interface is displayed on the mobile terminal device or on a vehicle auxiliary display, wherein the following features are transmitted:

[0014] o caller identity,

[0015] o emergency location, wherein the coordinates of the emergency location are determined by means of a global satellite navigation system of the vehicle or the mobile terminal device and are filled into the mask,

[0016] o situation image of the area outside the vehicle, which is generated by means of a camera equipped on the vehicle for the situation description,

[0017] wherein the interface is configured in such a way that the contact with the emergency call number cannot be terminated by a single operation, but requires at least two confirmations for termination.

[0018] According to the invention, an input mask is displayed on the interface, which requires the input or correction of the following features:

[0019] - caller identity,

[0020] - emergency location (for example by means of "what3words"),

[0021] - number of affected persons,

[0022] - number of vehicle occupants, and

[0023] - situation description,

[0024] wherein the caller identity is obtained from the driver card of the dashcam, the currently selected driver profile or the personal data on the mobile terminal device, wherein the map description of the emergency location is supplemented based on digital map data, wherein the number of vehicle occupants is determined by means of seat recognition and / or seatbelt lock recognition and by means of in-vehicle cameras, wherein the situation image is regularly updated every few seconds, and wherein the situation image is archived.

[0025] The solution according to the invention allows an accurate and fast emergency call to be made, wherein the rescue dispatch center obtains a more comprehensive situation report from the photographic image material.

[0026] For example, the vehicle can be configured as a van, a bus or a car. BRIEF DESCRIPTION OF DRAWINGS

[0027] Embodiments of the invention are described in detail below with reference to the accompanying drawings,

[0028] wherein:

[0029] Figure 1 a schematic diagram of a method of making an emergency call is shown. DETAILED DESCRIPTION

[0030] The only figure shows a schematic diagram of a method of making an emergency call in a vehicle.

[0031] In a vehicle equipped with a mobile terminal device (e.g. smartphone) and / or an auxiliary display, an interface 1 is displayed on the auxiliary display when an emergency call (e.g. 112 or 911) to a rescue dispatch center is made. The interface 1 has a mask that assists the caller in describing the emergency. The mask requires the following features to be entered:

[0032] - Caller identity: Who is calling? It can be provided that the caller identity information is taken from the driver card of the dashcam 2, the currently selected driver profile or the personal data on the mobile terminal device (e.g. Apple ID or Google user account) and pre-filled into the mask. Alternatively, the caller can also enter or edit the name manually.

[0033] - Accident or emergency location: Where is the emergency location? The coordinates of the vehicle and the emergency location are determined, for example, by means of a global navigation satellite system (GNSS) 3 of the vehicle or the mobile terminal device, and likewise filled into the mask. In addition to the coordinates, a map description can also be supplemented on the basis of data of a digital map 4 (e.g.: Autobahn A8, entrance xy, driving direction "north", at 53 km). The caller can also enter or edit this information manually.

[0034] - Number of people affected: The mask provides input options for this feature.

[0035] - Number of vehicle occupants: The number of people in the vehicle from which the emergency call is made can be determined by means of seat recognition and / or seatbelt lock recognition and / or by means of an in-vehicle camera. Alternatively, the caller can also enter or edit this information manually.

[0036] - Situation description: Situation images are generated and transmitted from the area outside the vehicle by means of at least one camera 5.1, 5.2, 5.3 (e.g. multifunction camera: MPC, MCS, SVS) equipped on the vehicle. The situation can be updated regularly every few seconds. It can also be provided that the image data is archived for subsequent investigation by the police.

[0037] The interface 1 can be configured so that the connection to the rescue dispatch center cannot be terminated by a single operation, but requires at least two confirmations to terminate the connection.

[0038] List of reference signs:

[0039] 1 interface

[0040] 2 dashcam

[0041] 3 satellite navigation system

[0042] 4 map

[0043] 5.1, 5.2, 5.3 camera
